What is Security+ 3.0 and does it block smart home hubs?

If you recently bought a Chamberlain or LiftMaster opener and cannot get it to pair with your smart home hub, the white learn button is why. Security+ 3.0 is a deliberate protocol change that cuts off all third-party wireless integrations. Here is what changed, what it blocks, and what you can do about it.

What Security+ 3.0 is and when it was released

Security+ 3.0 is the latest wireless protocol from Chamberlain Group. It appeared on new Chamberlain and LiftMaster openers in late 2025 and has been rolling out across retail and pro-dealer product lines through 2026. Models carrying the new protocol have been rolling out across both Chamberlain and LiftMaster product lines as older inventory sells through; confirm the learn button color on any specific model before purchasing.

The most visible sign of Security+ 3.0 is the white learn button on the opener head unit. If your opener has a white learn button, it uses Security+ 3.0. Every prior protocol generation used a different color:

• Green button: pre-1997, fixed code, no rolling code
• Red or orange button: Security+ 1.0, 1997 to 2005
• Purple or brown button: Security+ 1.0 or early 2.0, 2005 to 2014
• Yellow button: Security+ 2.0, 2011 to 2024
• White button: Security+ 3.0, 2025 to present

Security+ 3.0 uses 315 MHz radio combined with Bluetooth Low Energy (BLE) for pairing. The BLE layer is what enables the tighter control over which devices can connect. Prior generations used radio-only pairing, which made them easier for third parties to integrate.

What Security+ 3.0 blocks and why

Security+ 3.0 blocks all third-party wireless smart home integrations. Here is what will no longer work:

• Older myQ gateway (MYQ-G0401): the retrofit hub Chamberlain sold to add smart capability to openers that did not have it built in. It does not pair with Security+ 3.0 openers.
• Konnected blaQ in wireless mode: the local-control alternative to myQ that relies on wireless pairing with the opener. The wireless connection is blocked. The wired (contact-closure) mode still works.
• Standard universal remotes that were compatible with Security+ 2.0. These remotes cannot pair with the new protocol.
• Third-party smart home hubs (Home Assistant, Homebridge, Hubitat) that used wireless pairing to connect to prior-generation Chamberlain openers.

Chamberlain has not published a detailed public explanation for the change. The pattern follows the 2023 myQ API lockout, when Chamberlain blocked third-party apps from accessing the myQ platform. Security+ 3.0 is a deeper protocol-level change that prevents integration even before the cloud layer.

What Security+ 3.0 does support: the native myQ app, Amazon Key In-Garage Delivery, and Chamberlain's own smart home ecosystem. If you stay within the Chamberlain ecosystem, the opener works as expected.

The wired contact-closure workaround

The wireless block applies to radio and BLE connections. It does not apply to the wall button terminals on the opener. Those terminals accept a wired connection from any switch or relay.

A contact-closure relay is a small device that physically bridges the wall button terminals for a fraction of a second, simulating a button press. Smart home systems that support dry-contact input can trigger the relay via their own wireless connection to the home network, without ever talking to the garage door opener's wireless protocol.

The setup looks like this: the smart hub (Home Assistant hub, Konnected device in wired mode, Meross smart garage controller) connects to your WiFi or home network. When you tap "open" in an app, the hub sends a signal to the relay, which briefly closes the wall button circuit on the opener. The opener treats it as a button press and opens or closes the door.

This workaround fully bypasses the Security+ 3.0 wireless block. The opener never needs to pair with any third-party wireless device. The only physical connection is two wires from the relay to the same screw terminals used by the wall button.

For Apple HomeKit users specifically: the Meross MSG100HK is a HomeKit-certified garage controller that supports contact-closure wiring and works with Security+ 3.0 openers. It does not try to pair wirelessly with the opener. Instead, it uses a wired connection to the wall button terminals and a magnetic tilt sensor on the door to detect open/closed state. Once configured, the door appears in the Apple Home app and works with Siri.

How this differs from the 2023 myQ API lockout

In 2023, Chamberlain blocked third-party applications from accessing the myQ cloud API. At the time, apps like Home Assistant were using the myQ API to open and close doors remotely. Chamberlain cut off that access and limited the API to direct Chamberlain partners.

Security+ 3.0 is different in scope. The 2023 change was a cloud-layer restriction. Security+ 3.0 is a local wireless protocol change. It means even devices that do not use the myQ cloud at all, such as direct-pair universal remotes and local smart home hubs, cannot connect.

The two changes together mean that Security+ 3.0 openers cannot be integrated with third-party systems wirelessly or through the cloud. The only supported path is the wired contact-closure method described above.

Integration Method	Works with Security+ 3.0?
Native myQ app	Yes
Amazon Key In-Garage Delivery	Yes
Google Home (via myQ)	Yes
Alexa (via myQ)	Yes
Apple HomeKit (native)	No
Third-party universal remotes	No
Older myQ gateway (MYQ-G0401)	No
Home Assistant wireless	No
Wired contact-closure relay	Yes
Meross MSG100HK (wired)	Yes

Should you avoid Security+ 3.0 if you use a smart home system?

Not necessarily. The wired workaround works well and is not technically difficult. If you are having a new opener installed by a dealer, ask them to run the two wires from the wall button terminals to wherever you plan to mount your smart home relay device. That adds about 15 minutes to the installation and eliminates the compatibility problem.

If you are buying an opener yourself and plan to connect it to a third-party smart home system, confirm that the specific model you are ordering carries the yellow (Security+ 2.0) learn button, not the white one. Retail inventory is a mix right now as the transition continues. Check the product description or ask the seller before you buy.

One practical tip: if you buy a Security+ 3.0 opener and want to connect it to a contact-closure smart controller, mount the controller near the opener head unit, not near the wall button. The wall button wire runs from the opener head to the wall. Tapping into that wire at either end gives the same result. Mounting the relay controller at the opener end keeps the wiring clean and makes it easier to access the screw terminals without removing wall panels. A short run of 18-gauge two-conductor bell wire from the relay to the opener terminal block is all you need for most installations.
